# Compare Values of Logarithmic Scales

Calculator for the comparison of two values, whose size is measured in a logarithmic scale. At a logarithmic scale, the intensity doesn't grow linear, but exponential, it multiplies with every increment. Often, a decadic logarithm is used, that is to the base 10. If a value is increased by 1 (e.g. from 1 to 2 or from 5 to 6), then the intensity tenfolds. A value of 0 doesn't mean that there is no intensity, but usually, this is very low then.

Please enter three values to calculate a fourth one. For the base can also be entered e for the natural logarithm.

The formulas are: r = s^{a-b}, s = ^{a-b}√ r , a-b = log_{s}(r)

Example: for a natural logarithmic scale (base e=2,718281828459045), the value 6 is a bit more than 20 times as strong as the value 3.
